    Preface

    A Task Force on development of cold chain in India had been set up by the Ministry of Agriculture vide itsorder dated 3rdMay 2007. The said Task Force had recommended revised normative cost for cold storages andsubsidy norms for ensuring technology up gradation in cold storages. It has, therefore, been felt necessary todefine appropriate technical standards in respect of various components of cold storages without which exerciseof quantification of revised normative cost, subsidy norms etc cannot be substantiated; nor can the desiredresults o f effecting technology up gradation be achieved. Therefore, Department of Agriculture & Cooperation,Ministry of Agriculture, Government of India, vide its communication No. 22011/5/2007-M-II dated 16thJune2009 constituted a Technical Standards Committee (Annexure-I). Terms of Referenceof the Technical Standards

    Committee (TSC)is to give recommendations on the following issues-

    (i) Suitable technical standards and protocols for cold chain infrastructure in the Country

    (ii) The mechanism of implementation of such standards and protocols

    (iii) Any other issue that the Committee may consider important or relevant for the subject or maybe assigned to it by the Government.

    The Committee was given initial time frame of two months for submitting its recommendations. However,extension has been duly granted thereafter.

    TheTSC has classified cold storages for fruits & vegetables in following three main categories as listed below.

    (i) Cold storages for storage of fresh horticulture products which do not require pre-cooling(Technical Standards Number NHB-CS-Type 01-2010)

    (ii) Multi-commodity Cold storages for short term and long-term storage of fresh horticultureproducts, which require pre-cooling and varying storage requirements.Technical StandardsNumber NHB-CS-Type 02-201 0)

    (iii) Contro l Atmosphere (CA) Storages.Technical Standards Number NHB-CS-Type 03-2010).

    This volume of Standards covers Cold Storage of Type 01 mentioned above and has four sections viz. TechnicalStandards, Basic Data Sheet, Protocol for Implementation of the Prescribed Technical Standards and TypeDesigns. While firming up its recommendations by TSC , emphasis is laid on optimum energy efficiency andoverall performance and therefore coefficient of perfo rmance (CoP) is one of the determining criteria. In addition,

    aspects of environmental and safety concerns and Human Resource Development too have been taken in toaccount.

    The Technical Standards have general information on the type of produce that can be stored in particular Type/ module, their critical storage conditions, (as much compatible with the World standards as possible by relyingonWorld Food Logistic Or ganisation (WFLO)database in absence of research data for Indian conditions,except for potato, in terms of temperature, humidity range, CO

    2level, loading rate, pull down time, air circulation

    and ventilation requirement etc. In order to facilitate improved design, there is a detailed Basic Data Sheetavailable in the Section 2 of the Standards wherein plo tting different specification data into a system shall lead to

    vi

    better coefficient of performance from energy efficiency point of view. Section 3deals with the Protocol forImplementation of Technical Standards through system analysis of civil structure, thermal insulation andrefrigeration at the stage of issuing letter of intent and through site inspection at later stages.

    These standards and recommendations are intended to serve as minimum requirement, and are not to be construed

    as limiting good practice. Wherever IS-Code is not available, relevant standard codes of ISO / ASME / ASHRAE/IIAR or other International Codes have been followed. The responsibility for deciding whether other requirementsadditional to the ones listed in the technical standard document are necessary to ensure system integrity, efficiencyand overall safety, including operation, maintenance and servicing and/or the necessity to adopt additionalrequirements in the system design and construction to guarantee the overall performance, still rests with thesupplier / manufacturer.

    It is recommended that the suppliers / manufacturers shall furnish to the owner copies of instructions / manualwhich shall include operation & maintenance instruction, built drawings, wiring diagrams, recommended spareparts and replacement part list etc as recommended. It is also envisaged that the suppliers / manufacturers shallprovide training for the plant and machinery installed including safety and emergency procedures. The supplier/manufacturer will follow all practices set fo rth by Good Manufacturing Practices by various applicable Codesand Standards listed in this document and shall fully certify the equipment, plant and machinery supplied/installed in compliance to the relevant codes and standards which would be under scrutiny.

    Nonetheless, these also have provision for scope of variation, through aVariation and Am end m ent Clause, totake care of new concepts, innovations, and R&D in building design etc. so that improvements coming along theway are not stopped but analysed and incorporated in the design.

    The Committee acknowledges the valuable contribution made by experts in firming up its recommendationswhose particulars are listed inAnnexure-IIto the report; the list has special mention of non-member expertswho have volunteered and spared their valuable time in giving their inputs from time to time. In the end,Annexure IIIlists relevant BIS and other standards to which investors; contractors and suppliers may refer to

    comply with the requirements for designing and installing various components.

    TSC had invited comments to the draft standards by issuing public notice and has examined the commentsreceived from various stakeholders which are in respect of air-cooled ammonia compressors, Bunker-fin Coils,Electro Galvanisation and Hot Spray Galvanisation of MS cooling coils and Paddy Husk type thermal insulation,but in absence of authentic data, TSC recommends undertaking further investigation in to the claims andrepresentations received, before their incorporation in prescribed technical standards.

    Last but not the least, contribution made by Dr. R. K. Sharma - Senior Deputy Director, NHB has been ofimmense value as he for all practical purposes functioned as Member-Secretary to the Committee.

    Section-1

    Technical Standard No. NHB-Cold Storage-Type 01-2009

    1. Cold Storage Type :

    For fresh fruits and vegetables and other horticulture products which do not require pre-cooling butthere is crop specific rate of pull down and storage conditions,

    a. Fresh Potato Tubers for following purposes

    i. Early Crop (pre mature)

    ii. Seed Potato

    iii. Table Potato

    iv. Process Potato

    French Fries

    Chipping

    b. Onion, garlic, tamarind etc.

    2. Critical Storage Conditions :

    i. Quality of produce -Curing & pre-conditioning for about 7 to 10 days in the f ields for skin set/

    proper handling/ Application of CIPC.

    For example- it is recommended that potatoes are harvested at temps not lower than 8 C and

    not higher than 20 C and harvested potatoes are cured by keeping at 15 C to 20 C and 90%

    to 95 % RH for 5 to 10 days before placing them into cold storage, allowing the surface wounds

    to heal, thereby preventing water loss and protection from decay.

    ii. Commodity Storage Conditions-For designing a cold storage, product storage conditions

    must be defined in terms of critical storage conditions of temperature, relative humidity,

    presence of CO2, ethylene, air circulation, light etc. In absence of research data for Indian

    conditions, it is recommended to adopt commodity storage conditions as prescribed by

    Commodity Storage Manual of WFLO in absence of research data from Indian Institutions .

    Example - Design conditions for Irish Potatoes which are adopted, in absence of data for Indian

    potatoes are as given below.

    a. Temperature, storage period, relative humidity etc.

    Fresh Potato Temperature Storage Period Relative Humidity

    Early Crop 4 10C 0 3 months * 95%

    Seed Potato 3C@ 5 10 months 90 95%

    Table Potato 4C 5 10 months 90 95%

    For French Fries 7.2 10C 1 10 months ** 90 95%

    For Chipping 7.210C # 1 8 months ** 90 95%

    (*) If cured / wounds healed before storage.

    (**) Sprout suppressors must be used for long-term storage.

    (#) Generally stored between 9 - 13C as per WFLO manual whereas CPRI recommends 11C

    @ Based on expert advice of CPRI, which is firmed up by TSC after analysis of the same, critical storage temperaturefor seed potato is taken as 3oC 1o C. Moreover, one of the following two critical storage conditions for tablepotatoes may be taken into account after evaluating their implications on consumer preference for stored potatoesand cost of storage; firstly as critical storage conditions of potatoes for processing purposes and secondly, the

    critical storage conditions recommended for seed potatoes.

    a. 24 hours cooling to 15C followed by pull down rate of 0.5C per day till holding temperature

    of 11C 1C with CIPC application after first 30 days of storage; in this case stored potatoes

    may not turn sweet due to separation of sugar, however, storage cost will be higher due to CIPC

    application.

    b. 24 hours cooling to 10C, pull down to holding temperature of 3C 1C within 8 to days; inwhich case, starch accumulation will take place but storage cost may be lower,

    c. Temperature and humidity range:+/- 1C for temperature and humidity range as given.

    d. CO2

    level: Not more than 4000 ppm during loading and 2000 ppm during holding (source:

    industry).

    e. Loading Rate: 4% (at 25C) to 5% (at 20C) of the total storage capacity (equally split into

    chambers) per day so that total loading period is about 20 days. Temperature during loading to

    be maintained at 15 C which should be brought down to holding temperature @ 2 to 3 C per

    week; subject to choice of adopting CPRI recommendations as mentioned above.

    f. Pull-down time:24 hours for pull down to 15 C and @ 20 - 30 C per week for pull down to

    holding temperature. CPRI recommends that seed potatoes should be cooled to 10 C within 24

    hours of arrival at cold store and its temperature should be further pulled down to holding

    temperature of 3 C 1 C within 8 to 10 days as sugar separation due to rapid cooling is not a

    matter of concern for seed potatoes.

  • 7/21/2019 Cold Storage Guidelines

    10/79

    4

    g. Air Circulation:Minimum 50 CFM/MT of Potato (85 CMH/ MT of Potato) during the loading

    and pull-down period. However, during the holding period fan power is optimized by fan speed

    reduced to almost 70% by VFD control (which will reduce fan motor power consumption to

    34%) and thereafter automatic control will maintain temperature variation within each chamber

    at less than +/- 1 C throughout the storage period.

    h. Ventilation requirements in cold storage: it may range between 2 to 6 air changes per

    day to maintain CO2

    less than 4000 ppm. It is recommended to opt for mechanical CO2

    extractor with energy recovery system. It is a much better option than the present practice of

    opening the cold stores doors & hatch windows to ventilate and remove the CO2

    build-up as

    the later practice results in loss of energy, inability to maintain temperature variation range of

    1C, wetting of product leading to product loss.

    i. Lighting Condition: Dark

    j. CIPC application:For processing potatoes in general and for table potatoes if critical storage

    conditions equivalent to processing potatoes are adopted. CPRI recommends that due to

    slow pull down of temperature (0.5 C per day) in these situations, high holding temperature

    is built up which in turn accelerates germination of potatoes immediately after its dormancy

    period; therefore, CIPC application is recommended immediately after first 30 days of arrival

    of potatoes in cold storage. He further cautioned that rapid cooling should not be carried out

    for potatoes for processing purposes.

    3. Layout of a Typical Cold Store for Products Identified

    It is recommended to have multi commodity cold stores for better capacity utilisation. For example -

    a solely potato based cold storage may be designed for storage of seed potato and table potato or

    processing potato etc. Similarly, for energy efficiency, cold stores have to be multi chamber. It is

    recommended to have at least two chambers and chamber size should be of the capacity range of

    1,000 MT to 1,500 MT for ensuring uniform storage condition, proper capacity utilization, and energy

    efficiency. This is not possible in single chamber / larger chamber cold storages. Cold stores for of this

    type are generally with mezzanine floors, which must be provided with anteroom of adequate

    dimensions. Having staircase inside the chamber may reduce storage space and restrict possibility of

    having elevators and fire escape. Layouts with staircase in anteroom facilitate better space utilisation;

    higher efficiency of workmen, providing for elevators and fire escape but construction cost may be

    higher due to multiple doors etc. If CIPC is to be used as sprout-suppressor for certain products,

    then other chambers having products to be used as seed must be adequately separated by having

    separate anti chamber. Two typical layouts are given below.

    cooling units can be supported on floor mounted frame structure on

    top floor).

    Provision for FRP sheets for natural lighting to be made in roof sheeting

    at certain locations. For ventilation of attic, provision of ridge monitor or

    turbo ventilators (which require no electric power) can be made.

    Alternatively roof can also be designed by installing insulated roof panels

    with proper slope & sealing of longitudinal & lateral joints. The work to

    be handled by experienced agencies to ensure a trouble free roofstructure. The roof may be kept walkable for maintenance.

    Floor : The floor comprises of base concrete, in cold stores with suitably lower

    levels in cold chambers. The level difference between cold chambers

    and ante room to be equal to the thickness of floor insulation plus the

    layer of PCC or tremix finish,

    Strip curtains for cold rooms and Air Curtains for external outlets/ inlets:

    : Strip curtains are quite common for reducing infiltration of air during

    loading/ unloading. Air curtains need power for operation but are more

    effective if properly installed.

    Rodent proof civil structure and proper drainage of water to be ensured.

    Rooms for machines, Electricals etc.

    Dock : Loading & unloading dock shall be designed with RCC slab roof or sheet

    small canteen / electrical sub-station & D.G. set platform, roads & parking

    place for vehicles etc. Green landscaping with benches for labourers is

    desirable.

    4. Thermal Insulation:

    It is recommended that appropriate BIS standards are adopted for selection of design parameters (IS

    661:2000) and method of application of thermal insulation(IS 661 & 13205).Though fresh F & V are

    stored at + 0o C, it is recommended to design thermal insulation for (- 4o C to + 2o C) temperature

    condition to have lower heat load.

    Materials of thermal insulation and its application:

    Cold chambers have to be insulated on walls, ceilings / roofs & floors with proper insulating material of

    adequate thickness, with provision for vapour barrier on outer side & proper cladding/ cover on inner

    side. The commonly used insulation materials are:

    a) Expanded polystyrene

    b) Rigid Polyurethane foam

    c) Rigid phenolic foam

    d) Mineral wool / glass wool

    e) Extruded polystyrene

    The ancillary materials to be used include:

    a) Vapour barrier e.g. aluminium foil, polyurethane sheet, with bitumen / cold mastic adhesives

    Radiant barrier. This could be an option which the promoters can use for energy saving. However,the minimum thickness of insulation and the method of fixing will remain as specified in the standards.

    5. Total Refrigeration Load - Heat Load Calculation

    Procedure for load calculation

    Procedures laid out by ASHRAE Fundamentals and Refrigeration handbooks may be followed. The

    current method prescribed by ASHRAE Fundamentals is RTS (radiant time series) method in which

    room by room analysis for each hour is carried out. However, the assumptions used for the building

    envelope and the loads are very crucial. ASHRAE refrigeration handbook elaborates a more traditional

    approach. Thus, based on the overall impact/ sensitivity of important parameters, some estimates can be

    made. Designers also tend to take a safety factor of 5-10% on the estimated loads.

  • 7/21/2019 Cold Storage Guidelines

    17/79

    11

    Ambient conditions

    0.4% annual design conditions of that location as per ASHRAE/ ISHRAE data may be used for holding

    period. For the loading and pull down periods, 0.4% design conditions for those months may be taken.

    Product incoming temperature

    It varies with location and harvesting time. However, average value may be taken as shown in Typical

    Designs enclosed.

    Capacity during loading, pull down, holding and lean periods

    Refrigeration capacities should be calculated at various operating conditions and necessary arrangements

    for capacity control be included in the equipments to be provided.

    6. Refrigeration System & Equipment Selection

    Vapour Compression systems are commonly used. However, absorption systems can also be used for

    cold storages, where heat is readily available instead of electricity e.g. solar, geothermal, waste heat etc. A

    7.5TR ammonia-water absorption system was installed at Manikaran by IIT Delhi in 1980's. It worked on

    Geo-thermal energy.

    Refrigerant issues - eco-friendly, safety, energy efficiency

    Ammonia seems to be the best refrigerant in terms of environment (being natural) and energy efficiency

    for this application. However, it is toxic and precautions should be taken in its handling. In case there is

    a restriction of using ammonia at certain locations, the refrigeration system can be designed to work on

    R134a, R404A etc.

    Type of system - direct expansion (in case of HFC and others), liquid overfeed and

    gravity with a surge drum in case of ammonia:

    Liquid overfeed systems force excess liquid through the evaporator to improve the system

    efficiency and reduce the operating costs. It becomes more favourable as the number of evaporators

    goes up. Details of a gravity feed system are included in details on subsequent pages with list of

    additional equipment for a liquid overfeed system.

    Compressor - reciprocating/ screw with capacity control

    Multiple multi-cylinder reciprocating compressors or screw compressors with appropriate capacity

    control may be used. Typically the holding capacity may just be 50% of the peak capacity during

    loading. So, it may be suitable to go for two same sized compressors each suitable for holding

    capacity at peak loads. A third compressor as standby compressor is recommended. Compressors

    should be able to deliver the desired capacity at worst conditions not at rated conditions. VFD's

    can also be used for closer control in some cases. Capacity of compressor shall be confirmed by

    data- sheet of manufacturer.

  • 7/21/2019 Cold Storage Guidelines

    18/79

    12

    Condenser - atmospheric, evaporative, water cooled

    Condensers can be air cooled with water spray or with provision of pre-cooling of condenser air

    in case of HFC / HCFC or water cooled with S&T condenser and Plate Heat Exchanger ( PHE )

    with cooling tower arrangement in case of HFC / HCFC / Ammonia plant or of evaporative /

    atmospheric type in case of ammonia plant. Capacity of condenser shall be confirmed by data-sheet of manufacturer.

    Air Cooling Unit - ceiling / wall mounted- for cold stores

    Delta T (difference between evaporating and air inlet temperatures) should be kept low for

    higher humidity in the chamber. Typical values shall be 4.4 or less during holding period and can

    go up to 6 during peak loading period. This shall be confirmed by data sheet of manufacturer. This

    increases the coil surface substantially. The coils selected are kept on the higher side to keep

    higher humidity levels even during loading/ pull down periods. Ammonia coils are typically MS hot

    dip galvanised or SS/ aluminium tubes with Aluminium fins. The cooling units for other refrigerants

    have coils with copper tubes and aluminium fins. Coils with Aluminium tubes and Aluminium finscan also be used.

    Capacity control of fans

    Fans' operation can be cycled to save power during part load operation. VFD's may also be used

    on the fans to get good savings.

    Testing and Charging the system

    Installation, Testing & Commissioning should be carried out as per BIS (for standards available).

    ASHRAE standards may be referred to as guidelines but not mandatory.

    Air purger (manual or automatic)

    It is desirable to remove air and other non condensable gases from the refrigeration circuit to

    keep the compressor head pressures lower and also improve heat transfer coefficients.

    Defrosting method - water/ hot gas etc.

    Water defrosting is a simple method and can be done manually or through a timer.

    Humidification system

    Although higher humidity levels of 85-90% can be achieved by keeping low delta T in the coolingcoil. But during loading periods and for RH>90%, humidification system is a must. Several techniques

    are available, but it should preferably be done using water mist with 2-10 micron and uniformly

    distributed all over the chamber ensuring that the product does not get wet.

    Equipment derating at higher ambient

    A designer should match the loads with the de-rated equipment capacity at higher ambient

    conditions.

    and pull-down period. However, during the holding period fan power is optimized by fan speed reducedto almost 70% by VFD control (which will reduce fan motor power consumption to 34%) and thereafterautomatic control will maintain temperature variation within each chamber at less than +/- 1 C throughoutthe storage period.

    The ventilation air load is estimated based on 70% energy recovery using heat exchanger between theexhaust and supply air. The ventilation requirements range between 2 to 6 air changes per day tomaintain CO

    2less than 4000 ppm.

    Deal with adverse harvest conditions when the produce is wet, rotting, too cold or too warm

    Provide adequate and controlled cooling to maintain desired temperature and high humidity conditionsduring the storage phases.
